U 1 '2oolai s. (cues-175$ My present invention relates to machines for general materials the edges of which are to be pact; simplified self-containedpinking machine,"-

The invention" consists in the constructionf' "as white describedmor'e fully inftheifollowing" ries i i ml n gl f 9 li i ru 115a vertical Samantha a; ran i g which; for purposes; of illustration only, I: have shown a; preferredqembodiment :of mycinvention,

Ill denotes "a cloth-,platetwhich may be mounted liupoma'vrwork benchwa work atable or any other ,as tmi j j Manisew Pinking Attachment .Corp. New Stork, N. Y a corporation of Newlo'rk t appropriate support. The cloth-plate supports all parts of the machine. I

Rising fromtheright-hand endofthe clothplate is a vertical housing i in which are vertical and horizontal shafts l2and l3; respectively, the shaft l2 being mounted in bearings ll and I5, and the shaft J3 in bearings I6 and I 1Q Said shaft l3 for its "operation, has a pully l8 'which is connected by a belt (not shown) "toany'suitable T source of power. Through the intermeshing gear 10 i ing l9 and 20, the shaft I2 is driven fromthe shaft I3. v

Secured upon the cloth-plate by boltspr equivalent means is a casting body 2| having along' integralfarm 22, which," it will be observed, is spaced a distance above the cloth-plate soth'at there will be ample room for work'of various" kinds to be manipulated by the'operator'uponf f the cloth-plate below said arm. 23 is a'pressure f jaw which is disposed upon the arm22, its outer 2'0 end portion 24 extending downwardly along the outer end or the arm and beingsuitably bifur cated at 25 in order to carry the rotatable pressure roller 26. The jaw 23 is mountedfor vertical adjusting or yielding movement. It is provided 25 with a pivot screw 21 the plain or non-threaded lower end 28 of which fits in a socket in the arm 22 whereby through the manipulation of the nut The jaw 23 may move up and down on-adjusting pin 30 the lower end 3| of which is threaded into the arm 22. A' finger operated wing-nut 32 is threaded upon the upper portion of the pin and through its manipulation the tensional force of a coiled spring 33 may "be increased or decreased, said spring being coiled aroundthe Pinand imprisoned between the Wing-4 1 1; a itsseat 34'inthejaw. J

Rotatably located below the arm in" theclothg 4 plate is the bottom plnking cutter in 'the form of a disc-shaped member 35 having" upwg 1 presented teeth 36 adjacent its periphery, the present embodiment, the cutter is represented a as securedthrough a screw-31' to a; short vertical r "shaft 38 =rotatablein a bearing 39 fixedto"the cloth-plate. Said shaft 38 receivesits rotary" movement through the gears 40 and-4| "from underneath shaft 42 whi'chQintutri is operated through 'the gea'rs Band from vertical shaft=' l2. Suitable bearings l5, 4 n e to I cloth-plate, support the '"shaft '42. w

48 is a stationary shaft which is securedi 'in the present instance; to bearing 41 and supported thereby. Rotatably surrounding this shaft 1s a a.

sleeve 49 one end of which is fixed to gear 50 which is in mesh with gear 5| whereby to be operated from the shaft 42.

' upwardly-facing teeth of.the cutter.

cooperating with the pinking means to pink the For yieldingly cooperating with and frictionally driving the pressure roller 26, I provide a disc 52 having a large central opening surrounding the sleeve 49 and which is frictionally held between two disc shaped plates 53 and 54. A stout coiled spring 55 surrounds the shaft 48 with its outer end abutting a collar 56 so as to force the arrangement of discs tightly against one another with the disc 53 tightly pressing against the gear- 50. It is to be observed that the parts are so arranged that the driving disc 52 is frictionally maintained between the discs 53 and 54 and in such position that its milled periphery 51 will be in frictional driving and feeding contact with the surface of the pressure roller 26. In operation, the friction disc due to the pressure thereon of the roller 26 and of any work passing between these two parts is in an eccentric position but tends always to assume a concentric position.

From an inspection of Fig. 2, it will be noted that the driving disc and pinking cutter are arranged to operate in relatively close relation and in Fig. 1 it will be seen that the face of the pressure roller is relatively wide so that at the same time it engages the periphery of the disc and the Shaft 42 serves as means through which to transmit power for the cutter and for the roller, the latter under the arrangement being positively driven. The work, seized between the pressure roller above it and the driving disc and cutter below it, is smoothly fed and simultaneously pinked. Through the adjustment of wing-nut 32 the downward yielding pressure of the roller may be regulated in accordance with the conditions of work which are encountered. With my improved pinking machine, thin, delicate fabrics, relatively heavy fabrics and layers of fabrics may be pinked with equal facility, and it will be understood that the pinking operation takes place continuously with the feeding of the work.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the details of construction set forth but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
